Abstract:
A respirator that includes a mask body and a nose clip. The mask body is adapted to fit over the nose and mouth of a person, and the nose clip is placed on the mask body to extend over the bridge of the wearer's nose when the mask is worn. The nose clip has a predefined shape that comprises first and second wings. These wings exert a force resiliently inward on each side of the wearer's nose when the mask is worn. The invention eliminates the need for the wearer to individually shape the nose clip to the wearer's nose.
